Predictive Role of Fixation Stability for Clinical Stages and Conversion in Schizophrenia and Its Correlation with Cognitive Function.
Article in Schizophrenia bulletin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and hypothesisGiven that fixation stability is closely linked to cognition, we investigated fixation stability in patients at different stages of schizophrenia, its relationship with cognitive impairments, and its predictive role for conversion to psychosis. STUDY
designFixation stability was measured by bivariate contour ellipse area (BCEA), and cognition was assessed by the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery for 75 patients with first-episode schizophrenia (FES), 75 patients with clinical high-risk (CHR) syndrome, and 75 healthy controls (HCs). After a 1-year longitudinal study, CHR follow-up outcomes were classified as CHR-converters and CHR-nonconverters. Diagnostic model for clinical stages and prediction model for conversion were constructed using logistic regression and Cox regression, respectively. STUDY
resultsPatients exhibited fixation instability and cognition impairments compared to HC, with impairments increasing from CHR to FES. In CHR, BCEA negatively correlated with Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery scores, but this correlation was absent in FES. Diagnostic model effectively discriminated HC and FES, with an area under the receiver-operating characteristic curve of 0.914. Among 66 CHR followed up for 1 year, 13 have converted to schizophrenia, with a conversion rate of 19.70%. When divided into large and small BCEA groups (33 each), the conversion rate was 27.27% and 12.12%. Conversion prediction model achieved an area under the receiver-operating characteristic curve of 0.708.
conclusionsOur results indicate that fixation instability worsens with schizophrenia progression, which is associated with cognitive impairments. Additionally, BCEA may serve as a biomarker for predicting conversion to psychosis.
